The privately owned cargo ship splashed down in the Pacific on Tuesday, five hours after leaving the International Space Station. The California-based SpaceX confirmed the Dragon's return to Earth via Twitter.

The Dragon brought back more than 1 ton of science experiments and old station equipment. It's the only supply ship capable of two-way delivery. NASA is paying SpaceX for the resupply missions.

The unmanned capsule will be shipped to Los Angeles and then trucked to Texas for unloading.

SpaceX launched the capsule from Cape Canaveral at the beginning of March. Mechanical trouble delayed the capsule's arrival at the space station by a day, and bad weather at mission's end kept it in orbit an extra day.
